So i'm doing the Missing Master Brewer quest, and i've just found out from Korn that the brewer was put in the barrel and thrown out through the wall, and i need to follow the river, but i can't find him, i've been going through river to Cahbaet, and there were like too many dams and stuff for the barrel to swim through, but i can't find it, please could someone tell the exact location or show it on the map? Thanks
EDIT: OK i'm an idiot, i forgot to search first, and i found it in other threads, really sorry
